'Z'o all 'whom it may concern:

Be it known that I, J EAN THOMAS LEMAIRE, y

a subject oftheKingofBelgium, and a resident 'of Hodimont-Verviers, in the Kingdom of Belgium, have invented a new and useful Lap- Forming Machine, (for which I have obtained patent in Belgium, No. 49,902, bearing date November 24, 1879; in France, No. 137 ,222, bearing date June 12, 1880; in Germany, No.

x o 1 1,868, bearin g date June 10, 1880, and iu Anstria-Hungary, No. 21,815, bearing date September 24, 1880,) of which the following is a specification, reference being had to the accompanying drawings, wherein-- Figura 1 represents a front view of a machine embodyin g my invention when the mechanism is in the position shown in Fig. 3. Fig. 2 represents a side view of said machine during the process of laying the fieece upon the zo cylinder. Fig. 3 represents a side view similar to that shown in Fig. 2, except that in Fig.

3 the view is taken when the fieece lapped on the cylinder has attained the desired thickness and part of the circumference of the cylinder has been opened and the fieece broken through. Fig. 4 representsa transverse vertical section through the machine, showing`` the arm t in the position assumed by it when the traps are closed and just before the engage-` ment of said arm with tappet m; and Fig. 5

'rpresents a detail view of the horn o on shaft `s,'-''and proximate devices.

This invention relates to devices for doublingthe fieece as it comes from a carding-eu- 3 5 gine to form a lap or hat, which, when it acquires the necessary thickness, is toru open and passed to a second or finishing cardingengine.

In the accompanyingdrawings, a designates 40 a continuously-rotating cylinder, on which the fieece is wound in successive layers as it comes from the breaker. (Not shown.) The course of the fieece is indicated by arrow z, Fig. 3.

It passes between a roll, F, and cylinder a,

and is wound repeatedly around said cylinder.

When broken, as hereinafter described, the

bats thus formed are conveyed by a pair of `rolls, G G, away from'said cylinder. The roll gear-wheel, M, meshing with and drivinga i large gear-wheel, N, secured upon shal't a' of cylinder a and rotating the same, said wheel N in turn driving a wheel, O, the latter wheel engaging the teeth of a gear-wheel uponthe shaft o f said roll G.

A part of the periphery of thecylinder a consists of two hinged traps, y y, which close toward and nearl y against each other, and are provided with interineshn g toothed segments u u'. A helical retracting-spriug, '0, is attached by one end to one of said traps, and by the other end to the relatively immovab'le part of. the cylinder a. This spring operatcs to draw inward the trap to which it is-attached, and this motion is communicated through said segments to the other trap, both traps being thus closed, so as to form a part of the cylinder with no protruding portion. The proximate edges of these traps are provided with series of alternating' tecth, which are curved to engage with and tear or break the fieece (which has been lapped on said cylinder in successive layers by the rotation thereof,) when the said traps open outward. The trap to which the spring o is not attached is provided with a rigid arm, t, which is adapted to engage with an external object as the cylinder a rotates from right to left, the effect of such engagement ,being to open said "traps outward and break said fieece. If the external object referred to were permanent', the fieece would be broken at each rotatiou of the cylinder, and therefore it would never be lapped, and the object of my inventon would be defeated. It

is therefore essentialithat said object should be presented to said arm tonly once iu the course of a number of the rotations of said cylinder a. This 'number may be two, or it may be any greater number.

The object which I employ for the accomprevents said tappet from turning to the left` beyond the point of contact therewith. The spring e then yields, and the traps u and u' open until the arm t has ridden over and beyond the said tappet. VVhen this tappet mis turned down into a horizontal position it is out of the path of said arm t. The shaft sis provided with a eollar, fast thereon, having a horn, o, which is arranged to be struck by a stud, j, extendinginwardly from a gear-wheel, g. This wheel tnrns freely on shaft a' with roching or partly-rotary motions, caused by the positive action of a train of gears and a weight, i, acting in opposition thereto. These gears are driven from shaft a', as hereinafter explained. The weight is attached to acord passing over a pulley tur'ning with wheel g. The gears turn wheel g from left to right, and .the weight turns it from right to left, as shown in Figs. 2 and 3. At each motion of wheel g in the former direction the stud j strikes the horn 0 (see Figs. 4 and 5) from below, rocking shaft 8 from right to left, so as to raisettappet m into the path of rotation of arm t. The latter then carries this tappet into the position shown in Fig. 4, and the traps open, as before stated. VVhen the arm t rides past tappet m the stud j rides past horn 0. A Weight, Z, on a cord passing over a pulley, X, on rock-shaft 8, then turns the said rock-shalt from left to right, thereby restoring tappet m and horn` o to their first position. A stop-plate, w,limits the motion of the shaft 8 from left to right, in order thatl horn o may not pass out of the path of' oscillation of stud j. This plate is of angu'- lar form, one arm of. it being attached to the frame ofV the machine and slotted to allow of adjustment, as shown in Fig. 5. The other arm extends outward, so as to be struck by a cam-bar or lifter, n, fast on shaft 8. As the shaft 8 cannot turn farther from left to right after the lifter n is in contact with stop-plate w, the machine will be locked unless the stud j on wheel g can get below the horn 0 before the latter returns to its lowest position. To effect this the weightt' must be temporarily freed from the opposition of the `gears which drive said wheel g,.inasmuch as the force of the driving-shaft of course ovcrcomes said weigh t.V I' therefore contrive an automatic severance or unmeshing of the gearing, as follows: Said gearingconsists of aworm,b, which is fast on the driving-shaft a', a worm-wheel,

c, meshing with said worm and fast on an. up-

right shaft, d', a bevel-gear wheel, e, splined on the latter sha-ft near its upper end, another bevel-gear wheel, d, on a short shaftlturning in a fixed attachment of the frame, and a pinion, f, on this latter shaft arranged to gear with wheel g, aforesaid.

The splined wheel e is raised and lowercd on its upright shat't d'by means of a shippinglever,p, which is pivoted at its upper end to a stud projecting from the frame and extends downwardly, so that its lower end rests upon lifter n. This shipping-lever is provided with an arm which extends backward from its pivothub parallel to the body of said lever. Both the body of said lever and said arm enter-one on each side-an annular grooved formed around and in said wheel c. When the lifter n is turned from right to left its eccentric shape causes the shipper-lever p to rock upward on its pivot and move wheel e above and out of gear with wheel d. This occurs shortly before the shaft 8 is free to return to its normal position. As soon as the train of gearing is thus scvered the weight t' causes the wheel g to turn until the horn j has passed below the spot to be occupied by horn 0 when the latter returns to its lowest position. a This last action occur shortly afterward. The partial rotation of the wheelg, under theinfluence of weighti,islimited by'the contact of a stop-pin, k, extending inwardly therefrom, with a fixed plate or bar, Z, attached to the frame and preferablycurved, soas to hook against said pin in orderto effectually stop the rotary movement of'said pin and its wheel from right toleft. The position of said stop-pin on the wheel obviously determines the distance that hornj must travel before striking horn o, and consequently the length of fleeee that will be received by cylinder a, before the traps open to break it. A curvilinear series of perforations, 4, in the Wheel g allow said stop-pin to be shifted from one position to another around this wheel to regulate the action of the machine, as' above stated.

As the operation of all the parts have been fully described sert'at'im, with the reasons for each construction, combination, and arrangement, it. is not necessary to reeapitulate it here. The beveled construction of the end of arm t faeilitates theA turning backward of the cylinder when desired if the tappet m happens to'be in such a position that its anti-friction roller could come into contact with said arm on the cylinder, thus turning baekward.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The cylinder a, provided with hinged traps 11/ y in its circumference, formingpartofits convex surface, the arm t, attached to one of thev traps y, and the spiral spring v, attached to the other trap y, 'and the segments a u', attached to the traps 1/ y and meshing into each other, in combination with the tappet m, cam 0, catch j, wheel g, and. mechanism for Operating the foregoing parts, substant'ially 'as and for the purpose described.
